Systems and methods for defending against volumetric attacks, implemented in a cloud-based system. Embodiments include steps of, monitoring flows and a rate of requests to a Data Center (DC); receiving a request from an address to the DC, the request being for a service in a cloud-based system; determining if the address has been successfully authenticated within a past predetermined time period; responsive to the address not having been successfully authenticated within the past time period, and one of (i) the rate of requests being above a threshold or (ii) the number of flows being above a threshold, placing the address in a penalty box for a predetermined amount of time; and blocking requests from the address in the penalty box for the predetermined amount of time.

Defending against volumetric attacks

Systems and methods include receiving a request, in a cloud system from a first device, to access a second device; determining if the first device is permitted to access the second device; if the first device is not permitted to access the second device, notifying the first device the second device does not exist; and, if the first device is permitted to access the second device, stitching together connections between the cloud system, the first device, and the second device to provide access to the second device for the first device, wherein the connections are implemented through the cloud-based system.

Systems and methods for providing private application access via client to client and server to client communication through a cloud-based system

Techniques described herein convert mobile traffic between different types of VPN protocols, including IP and Transport. In an embodiment, a security proxy associated with a server receives a packet associated with a client app on a device, the packet including a source identifier and a destination identifier. The security proxy reassigns a tunnel identifier as the source and a node identifier as the destination, then stores a correlation of the tunnel identifier, the source identifier, and the destination identifier. The security proxy forwards the packet to the node inside the security proxy, and determines the destination identifier based on the correlation. The node then forwards the packet to the destination. This allows for multiple devices to use a same source identifier, e.g., same IP address. In some embodiments, a secure connection is established and/or the device and server are mutually authenticated prior to the processing of the packets.
